Blog Spam: the changing face of spam

In this lecture there will be a general discussion of what blog spam, 
referrer spam and other web content poisoning spam is. Then we will 
cover some examples, show what the bad guys are doing and some 
technologies they use to accomplish it, while on the other hand, what 
technologies are being used to combat them.

19:10 - Break
Drinks and light food will be served, free of charge.

Leapfrogs and Honeypots: Distributive defense against computer viruses

Although computer viruses cause tremendous economic loss, defense 
mechanisms fail to adapt to their rapid evolution.
Previous immunization strategies have been characterized as being static 
and centralized, which has made virus containment difficult or even 
impossible.
We suggest, instead, to propagate the immunization agent as an epidemic.

The main problem with epidemic vaccine propagation is that it is bound 
to lag behind the virus.
We suggest to give the vaccine an advantage over the virus by allowing 
it to leapfrog through a separate, overlapping, partially correlated 
network.
This enables the anti-virus to contain the epidemic efficiently.
We systemize this concept with a 'honey pots' architecture which 
achieves both early virus discovery and rapid immune disseminon.
We present analytic, as well as simulation, results for a set of 
realistic topologies that illustrate the effectiveness of this approach.

Attendance is free.
